As far as YYC/YYZ route goes, I am with you. My bet is that J/C/Z accounts for +/- 25% of the cabin. I don't pay a lot of attention to other routes, so I won't speculate. But I see very similar consumption patterns. And a high percentage of my flights on this route over the last couple months have been R>0 up to day of departure.
